"O Christmas Tree", also known as "O Tannenbaum" in Germany, is a traditional Christmas carol of German orgin. It was written in 1824 by Leipzig organist, teacher and composer Ernst Anschütz, and became associated with the Christmas tree in the early 20th century.

It is the first of three songs in the episode "Jay Jay's Christmas Adventure". It was sung at the end of the first part, led by Big Jake and joined by Jay Jay, Snuffy, Tracy, Herky and Brenda Blue. They do this every year as a tradition after they light the Christmas tree.
